Application filed November 16, 190

To all whom, it may concern: Be it known that I, MAX GARBEIL, acitizenof the United States, residing in the city and county of Philadelphiaand State of Ienn sylvania, have invented certain new and usefulImprovements in Machines for Making Buttons, of which the following is aspecification.

This invention relates to machines for the manufacture of buttons ofmother-of-pearl, horn, or similar material, my principal object being toprovide a simple and eificient construction and organization ofmechanism whereby the application of the disks or blanks I5 to,theirtreatment upon, and subsequent removal from the machine may beexpeditiously effected.

The invention, as generally stated, comprises a novel construction andarrangement of work-holding chucks and supporting and actuatingmechanism therefor, together with tool supporting and operating devicesand certain other novel features of construction and combinations ofparts, which will be here- 2 5 inafter particularly described andclaimed.

In the drawings, Figure 1 is a plan of ,my improved machine. Fig. 2 is aside elevation thereof. Fig. 3 is a transverse section, as on the line 33 of Fig. 1-. Figs. 4 and 5 are devel: o opments of the upper and lowergear-wheels, respectively, for effecting the intermittent rotation ofthe chuck-bearing shaft. Fig. 6 is a longitudinal section, enlarged,through one of the chucks and its adjuncts. Fig. 7 is an elevation ofone of the chucks removed from its sleeve or casing. Fig. Sis a verticalsection, enlarged, through the tool-holder and its supporting andoperating parts, as on the line 8 8 of Fig. 1. p

A represents the supporting-frame, comprising the bed 1 and standards 2.3 is the main shaft, having its bearings in brackets A on said frame andbeing equipped with the fast and loose pulleys 5 6, respectively. On therespective ends of the bed are pedestals 7, provided with suitable boxes8, in which are journaled the respective ends of alongitudinally-disposed shaft 9. Keyed or otherwise secured on thisshaft is a spiral gear 10 of special construction, with which coacts aspecial gear 11 on a lower transverse shaft 12, having its hearings inbrackets 13 on the bed-plate. On one end of the shaft 12 is a bevelwheel14, in mesh with a similar wheel 15 on a vertical shaft 16, having itsbearings in abracket 17, depending from the bed-plate. The lower end ofthe shaft 16 carries a bevelwheel 18, which also coacts with a similarwheel 19 on the main shaft. Hence when power is applied to the mainshaft the motion is transmitted therefrom through the intermediategearing to the transverse shaft 12 and thence through the gears 11 and10 to the longitudinal shaft 9. The construction of the gears 10 11 issuch that the shaft 9 is intermittently rotated thereby and alsotemporarily locked at the end of each step or movement. In thepresentinstance the shaft 9 makes one-third of a revolution during eachmovement thereof. The peripheries of the two gears are shown developedin Figs. stand 5, by reference to which it will be observed that atregular intervals the spiral or inclined teeth of the upper wheel 10 arereinforced and mutilatedthat is, at each place two adjacent teeth arethickened and foreshortened on opposite sides of the wheel to afford atransverse interdental space, as indicated at 10, and it will also beobserved that the lower wheel is provided with a few spiral teeth only,the remainder of the periphery being provided with a circumferential rib11. WVhen the teeth of the lower wheel are in engagement with the teethof the upper wheel, the latteris rotated thereby one-third of arevolution; but when the rib of the lower wheel registers with thetransverse interdental space such rib locks the upper wheel in placeuntil the teeth reugage the teeth of the upper wheel, in which case thelatter is turned another third of a go revolution, when it is againinterlocked with the rib, as before, and so on the upper wheel isintermittently turned and locked by the lower Wheel.

Affixed to the shaft 9 are two heads 20, which conjointly constitute achuck-bearing frame, in which are j ournaled at equidistant points fromthe axis of the shaft three rotatable sleeves 21, Fig. 6, each of whichsleeves is provided in the space between the two heads with a flangedwheel 22. Passing about the uppermost wheels is a belt 23, which alsopasses around a large driving-wheel 24 below the bed-plate. The wheel 24is carried by a shaft 25, journaled in the free end ofa frame 26, whichis sleeved on the main shaft. On the two shafts are sprocket-wheels 2728, respectively, which are geared together by a chain 29, whereby theshaft 25 is positively driven from the main shaft and the motion istransmitted from the shaft 25 to thefianged wheels 22,about which thebelt 23 passes,there by rapidly revolving the sleeves carrying saidwheels. It will be seen that the frame 26 will rise and fall during theintermittent rotation of the chuck-frame and that the belt 23 will bethereby maintained in operative engagement with the two uppermost wheelsin the latter frame.

At the inner ends of the respective sleeves are chucks 30, which areadapted to receive and hold button-blan ks. Each of these chuckscomprises a longitudinally-split tube 31, provided with a screw-threadedportion 32, that is screwed into an internally-threaded portion of thesleeve. The split portion of the tube projects beyond the sleeve andconstitutes a series of clamping-jaws, which are socketed, as at 33, forthe reception of the button-blank. The normal tendency of the jaws is toseparate or open, and hence means are provided to close the same andeffect the clamping of the work therebctween. To this end the jaws areformed near their acting portions with beveled surfaces 34, which areembraced by a correspondingly-beveled annulus 35, which is slidinglyfitted within the forward end of the sleeve. By retracting this annulusthe beveled surface thereof coacting with those of the jaws will forcethe jaws to gether, and by returning the annulus the jaws being freewill resume their open or normal position. Extending axially through thesleeve and thechuck-tube is a spindle 36, provided at its forward endwith atransverse pin 36,which is connected with the annulus. Therearward end of the spindle extends outwardly of the sleeve and isprovided with a collar 37, between which and the sleeve is interposed astout spring 38, that tends normally to retract the spindle and annulus,and thereby close the jaws. By this construction it will be seen thatthe acting or clamping portions of the chucks occupy at all times thesame vertical plane regardless of variations in the diameter of theblanks applied thereto and that therefore the position of such blanks inrespect to the turning-tool (hereinafter described) to which they arepresented is always uniform.

Rising from the bed-plate rearwardly of the chuck-frame is a post 39,provided with a cam 40, that lies in the path of the rearward ends ofthe spindles during the intermittent rotation of said frame. Thus thespindles successively engage the opposing cam and are pressed inwardlythereby to effect the release of the chuck-jaws. At each dwell of theframe the spindle is maintained retracted by the action of the cam, andthe jaws controlled by the particular spindle are therefore in openposition for the reception of a button-blank. In the next succeedingmovement of the chuck-frame the spindle, escaping the cam, resumes itsnormal or retracted position, and the blank is thus clamped by andbetween the jaws. At the same time another spindle engages the cam andthe above-described operation is repeated, and so on successively theadvancing spindles engage and escape the opposing cam. Mounted on thebed forwardly of the chuck-frame and on the side thereof diametricallyopposite to that where the cam is located is a slide-rest 41, to whichis fitted a slide 42, carrying a turning bit or tool 43, that isdesigned to act upon and shape the face of the rapidly-rotatingbutton-blank opposite thereto in one of the uppermost revolving chucks.The slide is reciprocated toward and from the chuck-holder atpredetermined intervals in a manner to act upon the successive blanksduring the stages of rest of the intermittently-rotatable holder. Whenthe chucks are opened through the instrumentality of the cam 40, asabove described,the turned buttons are removed there from by theattendant, and other blanks to be turned are then applied to the openchucks. In the present instance the slide-rest is provided with arearwardly-extending rod 44, which is maintained yieldingly in contactwith a cam 45 on the shaft 12 by means of a retracting spring or springs46, secured to the slide and to one of the pedestals 7, the peripheralcontour of the cam being such as to effect the progressive advancementof the slide toward the button-blank and then to release the slide topermit the spring to retract the latter. A set-screw 47, fitted in theslide, acts against the opposingextremity of the rod to permit relativeadjustment between the rod and slide. (See Fig. 8.)

The tool 43 is fitted to an inclined guideway in the forward face of theslide and is therein adjustable in respect to the plane of thebutton-blank, as need may require. The butt of the tool rests upon atapped block 48, through which extends a suitably-disposed set-screw 49,carried by a bracket 50, bolted or otherwise secured to the slide,whereby when said screwis manipulated the block may be raised orlowered, as desired, to accomplish the corresponding adjustment of thetool. This tool extends freely through a transversely-slotted bolt 51 inthe slide, so that by properly turning the screw-nut 52 of the bolt thetool may be released preparatory to adjustment and may then be clampedin the predetermined position of adjustment.
